If both [heaven and hell] are “eternal,” it follows necessarily that either both are to be taken as long-lasting but finite, or both as endless and perpetual. The phrases “eternal punishment” and “eternal life” are parallel and it would be absurd to use them in one and the same sentence to mean: “Eternal life will be infinite, while eternal punishment will have an end.” Hence, because the eternal life of the saints will be endless, the eternal punishment also, for those condemned to it, will assuredly have no end.
